It provides a taping head readily granted December 5, 1933.Briefly described,'th'e The present invention provides an apparatus ofin effecting the paying-off of tape from apack- 5;;

When the winding of the tape begins in one or the sameposition, that is, so that the the tape (in the form of a loop) mustpull upon mid-planes of tape packages of diiierent Width the tension armwith a force of at least five The invention further provides a tapinghead the spring 38 begins to flex.

The tension-lever26 also operates 28 on the tension lever 26, then over the guide on thebrake 22 through an arm 32 thereon, to 4| to the winding guide G andfrom thenceonto which arm 32 one end of a brake-band 34 is atthe cableC.

55., tached. The. construction and operation of the 'I 'he spindle 20 ofthe packagesupport I2 turns in bearings 44 mounted on a part of theflyer F, and as the flyer turns, the package support I2 and spindle 20turn to pay-off tape from the tape package T as tape is wound onto thecable C. The turning of the package support I2 and spindle 20 is againstthe frictional resistance of the brake 22 regulated by the actionthereon of the tension lever 26 and spring 38, as hereinbeforedescribed.

According to the present invention the taping heads are so constructedand arranged that the mid-planes of tape packages T of different widthlie in the mid-plane of the package holder, designated by the line MP,Fig. 1, and the arrangement of the guides 40, 4| arm 28 and Windingguide G is such that the center lines of tapes t of different width runover the said parts, at the same points. The effect of such constructionand arrangement is that tapes of difierent width may be applied smoothlyin either a lap wrap or a butt wrap without buckling, and under tension.

To this end the plates are provided with a means 50 for positioning theplates I4 and I5 so as to position and hold the tape packages T ofdifferent width with the mid-planes thereof in the mid-plane MP of thesupport I2. The means 50 for positioning and holding the plates I4, I5as aforesaid may, as here shown comprise a pair of nuts 53, 54 arrangedwithin the hub I8 and engaging. an oppositely threaded screw 56.Suitable connections are provided between the nuts 53, 54 and plates l4,I5. To provide for the replenishment of tape packages in the holder I2,the connection between theoutside plate I5 and the nut 54 at the outerend of the hub, is a detachable one. As here shown the inner plate I4 isconnected to the nut-53 by means of one or more lugs 58, which latterpass through a longitudinal slot or slots 59 to the inner side of thehub.

The detachable connection between the outer plate I5 and the nut 54 maycomprise one or' more lugs 62 projecting from the plate I5 through aslot or slots 64 in the outer end of the hub into a position to beengaged by the nut 54. 'As here shown, the lugs 62 may be. provided on aring 66 which is fastened to the plate I5 by screws or the like asindicated at 68, Figs. 1 and 4. Each slot 64 has an ofiset portion 64*running through the end of the hub I8. Nut 54 is provided with one ormore slots It each of which is in alinement with the offset portion 64of a slot- 64. The nut 54 may be prevented from turning by means of aSlot I4 therein and a key or rib I6 runninglongitudinally along the inside of the hub I8.

Any suitable means may be provided for turning the oppositely threadedscrew: 55.

attached to the outer end of the screw 56,and having a nut 82 thereonwhich may be engaged by a wrench for turning the said screw 55.

The hub may be provided with transverse fins 85 for engaging and holdinga tape package against rotation on the hub. As the moment between thetape and the hub, when the tape pays ofi from the circumference of atape pack-,

As here. shown the turning means comprises a cap 80,

engagement with the sides of the tape package T, and for betterefiecting the clamping action, the inner faces of the plates I4 and I5may be provided with a plurality of radial ribs 88.

The action of the oppositely threaded screw 56 and the nuts 54 is tomove the plates I4, I5 symmetrically toward the mid-plane MP.Consequently tape packages of diiTerent width will be supported and heldin the'package support I2 with the mid-plane packages all lying in themidplane MP of the package support.

To replenish the taping head, the oppositely threaded screw 56 is turnedto bring the nut 54 to a position where the lugs 62 on the outer plateI5 may enter the oifset portion I54 of the slot 64. The nut 54 is shownin the position just described in Fig. 4. The plate I5 and the lugs 62thereon are thenslid longitudinally from a position a Fig. 7 to positionb Fig. 7, then rotated from position b to the position 0 in the offsetportion 64 of the slot, and then slid off of the hub through slot 64% asindicated at positions d and c, Fig. 7. The spent tape package is thenremoved, and a new package placed onto the hub. .Plate I5 is thenreplaced on the hub and brought to a position where it will again beengaged by the nut 54 by the reverse of the movements just describedwithreference to Fig. 7. When the plate is in position and the lugs. 62thereon arein the portion of the slot 64 beyond the offset portion, theoppositely threaded screw 56 is turned in a position to move the platesI4, I5 toward the mid-plane MP and thereby position and hold thereplenishing tape package T in the support I2 with its mid-plane in themid-plane MP of the support I2.

The invention may receive other embodiments thanthat herein specificallyillustrated and described.
